Membrane separation techniques are used to separate certain components (protein, fat, water, etc.) in liquid products such as milk and to obtain these components in pure form, and also to remove microorganisms in these liquid products. In addition, these ... see more

Polymer inclusion membrane (PIM) has recently evolved as an alternative separation technique to conventional solvent extraction as it eliminates the use of toxic solvents, reduces separation cost, and simplifies the separation process. PIM is the new gene... see more

Natural gas is predicted to be a potential energy source in the future. However, the presence of carbon dioxide in it causes corrosion of transportation pipeline and reduction of calorific value.  Various separation technology such as adsorption, abs... see more

An asymmetric lanthanum doped ceria (LDC) membrane was prepared by sintering process. The membrane consisted of two layers, dense LDC and porous Ni-LDC layers with a total thickness of approximately 850 μm. According to the XRD pattern, sintering process... see more

The separation mechanism of proteins on a charged ultrafiltration membrane was analyzed using the extended Nernst–Planck (N-P) model. The model was solved numerically based on experimental data during ultrafiltration of bovine serum albumin/BSA and hemogl... see more

Pure ZnO and composite ZnO-CeO2 coated thin films on titania substrates were prepared using a chelating sol-gel method under controlled conditions to be used in the separation and/or rejection of Se(IV) and Cr(VI). XRD and SEM studies confirmed the format... see more

Olefin/paraffin separation is an important technological process. A promising alternative to conventional energy-consuming methods is employment of gas-liquid membrane contactors. In the present work, the membranes used were polysulfone (PSf) asymmetrical... see more

Gas membrane-based separation is considered one of the most effective technologies to address energy efficiency and large footprint challenges. Various classes of advanced materials, including polymers, zeolites, porous carbons, and metal–organic fr... see more

Polyvinylidene fluoride (PVDF) is a popular polymer material for making membranes for several applications, including membrane distillation (MD), via the phase inversion process. Non-solvent-induced phase separation (NIPS) and vapor-induced phase separati... see more
